DROP-WIRE FOR DOUBLlNG-MACHINES, 80G.

SPECIFICATION forming part of Letters Application filed December 15, 1880.

To all whom it may concern:

Be it known that 1, CHARLES E. CLARK, of Canton, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Drop-Wires for Doubling-Machines, &c.; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure l is an end view, Fig. 2 a top view, and Fig. 3 a side view, ofa drop-wire provided with my invention. Fig. 4 is a perspective view of the movable thread-guide of the dropwire, Fig. 5 being a side view of the drop-wire without the guide.

With my invention a guide, on becoming too much worn by the thread while being drawn through it, can easily be removed from the head of the drop-wire'and another or unworn one substituted.

Heretofore when the loop or guide of a dropwire has become so worn, it has been customary to cut it from the wire and replace it by a fresh loop, soldered or otherwise secured or immovably fastened to the wire.

In carrying out my invention, the drop-wire shown at A in the drawings, instead of being formed with a thread-guide atits end, has there a tenon or projection, a, arranged or bentvat a right angle to the part of the wire below it.

The guide B, I usually form of a single piece of round wire, bent at its middle in a helixcoil, as shown at b, the two parts or arms 0 d of the wire being arranged at a right angle, or

thereabout, to each other, and terminating in hooks e f, as shown. On the tenon of the dropwire beinginserted within the bore of the helix, and the catch-arm 0 being hooked upon the drop-wire, in manner as shown, the guide B becomes connected with the wire, and can be removed therefrom at pleasure.

Although I prefer to make the guide of a single piece of wire, in manner as shown, it may be otherwise constructed, so long as it has not only the socket for receiving the tenon of 5 jecting from the coil arranged at or about at a right angle to each other and hooked, substantially as set forth.

3. The combination ofthedrop-wire provided with the projection or tenon, as described, with a removable thread-guide socketed to receive the tenon and having a spring-hook to catch upon the wire, all substantially as set forth.

CHARLES E. CLARK.
